This manual explains the reasons behind the instability of your Bitmain Antminer L7 and how to fix it.
Abnormal Performance
- The Bitmain Antminer L7 miner restarts automatically
- The hashrate is unstable
Reasons and Solutions
- Due to its electronic nature, the Bitmain Antminer L7 is susceptible to electromagnetic interference. If the control signal is disrupted, the miner might restart. The chip or hash board may behave abnormally when it is interfered with. Grounding and shielding can help prevent it from happening, and restarting typically restores it.
- It’s hard to rely on the power supply. The power output of the hash board can reach 200 to 300 A when the Bitmain Antminer L7 is running, and the liquid cooling miner has a higher power output. Since the hash board will restart when the power output varies significantly, it is challenging to determine when this occurs. Typically, you can try switching the power source.
- voltage is either low or unstable. To check for this problem, you’ll need specialized equipment or an accomplished electrician.
- Damage is done to the control panel. The control board is the center of the miner, which is equivalent to a microcomputer. Flash memory contains firmware software. The miner will have to restart due to the control board issue. Normally, it can be reset to its factory settings. Also read: Bitmain Antminer L7 Flash Card Tutorial
- In general, the chip can be found by searching the log, but this method is unstable. The chip may be returned to the manufacturer for immediate repair if it is broken or unstable. Read more about what to do if the log shows chips lost.
- Due to the network’s unpredictability, there is a possibility that the Bitmain Antminer L7 will restart. For local inspection, you can typically try switching the network cable or network port.
